Where are they?
Ever since human beings have been aware of our place in the universe, we have been searching for signs of extraterrestrial life, specifically intelligent life. However, despite our best efforts and certainty that it is unlikely that we are alone in the galaxy, we still find ourselves asking: “Where are they?” With modern scientific knowledge, … Continue reading Where are they? → Continue reading
Wobbling Stars
Most people would be surprised to know that every star in the sky is not a “stationary” center of their solar systems.

But many would look at the Sun and say that relative to the rest of the Solar … Continue reading Wobbling Stars → Continue reading
A Universe From Nothing
Lawrence Krauss is a cosmologist and theoretical physicist famous for being one of the first scientists to posit that most of the energy of the universe resides in empty space. The video above is called “A Universe from Nothing” and I would like to comment on a few parts of the video that will hopefully encourage you … Continue reading A Universe From Nothing → Continue reading
Why is gravity so weak?
Gravity is a fundamental force that holds together our solar system, our galaxy, and every person to Earth. It must be pretty strong to hold something as massive as Jupiter in orbit right? Actually, compared to the three other fundamental forces, gravity is unimaginably weak. To demonstrate this, use a common refrigerator magnet to pick … Continue reading Why is gravity so weak? → Continue reading
Historical Astronomers in Context
Galileo Galilei (15 February 1564 – 8 January 1642), often given the title “father of astronomy” or even the “father of science,” lived during the start of modern science and faced much persecution for his contradiction of commonly held Aristotelian cosmology. The 16th and 17th century were very tumultuous times in Western history. The end … Continue reading Historical Astronomers in Context → Continue reading

The slowness of the speed of light
Warp Speed The speed of light is about 3*10^8 m/s, or in more recognizable units, over 670 million miles per hour. To observers on Earth, this is unimaginably fast and allows us to communicate almost instantly with anyone, no matter where they live. In fact, light can travel around Earth over 7 times in a … Continue reading The slowness of the speed of light → Continue reading
